Giant impact theory
The Moon was formed from the collision between
Earth and another Mars-sized body.
colliding planetesimbols hypothesis
The Moon was formed from collisions and combining
of planetesimals.
capture hypothesis
The Moon was locked into orbit by Earth's
gravity as it was passing by it.
accretion hypothesis
The Moon was formed from the same cloud
of material as Earth.

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
